OPERATING
Gradual start and overload protection
The machine is equipped with electronically controlled gradual start and overload protection.
* If the system has shut down due to overheating, the lamps will continue flashing until the system has cooled down and
is ready to be restarted.
The electronics cut the current immediately if the blade jams.
Managing dust
Water cooling must always be used. Dry cutting causes immediate overheating and machine and cutting blade failure
with a risk of personal injury.
Adjust water flow using the tap to bind the cutting dust. The volume of water required varies depending on the type of
job at hand.
If water hoses loosen from their supply sources, this indicates that the machine is connected to a water pressure that is
too high. See instructions under the "Technical data" heading for recommended water pressure.
